FIR Coefficient Finder is a digital signal processing tool which quickly generates floating point and fixed point coefficients for Finite Impulse Response filters. Supported filter types include low pass, high pass, band pass, notch, raised cosine, and root raised cosine. Generation methods include windowed filter design, and remez-exchange.

Analysis features include magnitude and phase plots in the frequency domain, as well as impluse response plots in the time domain. Zoom features and cursors make taking measurements quick and easy. Comparison plots between floating point and fixed point coefficients allow you to obtain the optimal coefficients for your needs.

Here are some key features of "FIR Coefficient Finder":
Quickly Design FIR Filters
Floating Point - Fixed Point Conversion
Multiple Filter Types
Window and Parks McLellan algorithms
Time and Frequency Plots
Cursors To Measure Performance
up to 2047 coefficients.

Limitations:
FIR Coefficient Finder Demo runs just like FIR Coefficient Finder Pro, but does not allow you to view the coefficients, or save and load filters, and is limited to 16 coefficients.

Requirements:
Display : 1024 x 768 or higher
Processor : PPC G5 or better, PPC G4 - 1GHz or better, Intel Core Duo or Core Solo
Memory : 512 MB recommended.

What's New:
bug fix to prevent application crashing under certain conditions
added installation program
added feedback request link
updated licensing setup
